From this post about Bret Victor:
The sorts of things I saw the capital-D Designers concerned with left me really cold."
It seems clear that at this point in his career Victor had mastered what he calls the Way of the Electron, the Way of the Algorithm, and the Way of the Interface — "the Yang of technology" and "the Yin of Design" — but had found all of these to be false paths. Victor needed some time off for reflection, for finding his own path.
